Kwik Delivery Company Buys a Truck from Lucky Vehicles, Inc

Kwik Delivery Company buys a truck from Lucky Vehicles, Inc., under a guaranty signed by Mina, Kwik's president, who writes "President" after her signature.

B) Lucky, because Mina works for Kwik.
C) Mina, because she did not intend to be bound by the guaranty.
D) Mina, because she signed only as a corporate officer.
